Associate correct tags when using blueprints prefixes

[AlexisNo]

When configuring sails.config.blueprints.prefix and/or sails.config.blueprints.restPrefix, the controller tag was not correctly retrieved. Subsequently, the paths appeared in the "default" section of swagger-ui instead of a section having the API name.

This PL returns the corresponding tag when the first of these conditions is fulfilled:

• blueprints.prefix and blueprints.restPrefix match the route and a controller tag is found
• blueprints.prefix match the route and a controller tag is found
• blueprints.restPrefix match the route and a controller tag is found
• a controller tag is found

Whatever the configuration of sails.config.blueprints.prefix and sails.config.blueprints.restPrefix is, the path with be associated with a correct tag.
